印尼农业的技术效率和远期生产增益

一、引言本文目的是评定印尼粮食经济今后能否借助农户技术效率的提高来增大生产效益。下面我们将检验关于种值水稻和杂粮作物(木茨、花生和豆类)的印尼农场抽样样本的技术效率。此外,我们也将评估技术效率、农场规模和农场位置的关系。     

货物销售 货物所有权的转移

有关货物所有权转移的法律规定是至关重要的,因为就所有权的转移而论、买卖合同的当事人通常不会表明他们的意图。加之,所有权一转移,风险也就转移,总而言之,只能提起与损害赔偿不同的价格诉讼。以下是有关的法律规定: 特定货物我们要考虑六种情况。 (1)第17条规定,凡特定或确定货物的买卖合同,就在双方愿意货物所有权转移之时,这些货物的所有权转移了。于是,为了确定双方的意愿起见,必须重视合同的条文,     

DNA typing: an accessory evidence in doping control

A clear positive case for anabolic steroids doping was confounded by alleged urine tampering during doping control procedures. Review of the chain of custody showed no flaws, but nevertheless the athlete was adamant that the urine sample should be analyzed for DNA in order to support her contention that she was not the donor of the sample. The results obtained showed that the urine sample that scored positive for steroids contained nuclear DNA that could not be matched to the DNA obtained from the athlete's blood. On the other hand, the same urine sample contained mitochondrial DNA whose nucleotide sequences spanning the hyper variable regions HV1 and HV2 proved to be identical to those determined in mitochondrial DNA amplified from the athlete's blood. The occurrence of an extraneous genotype is compatible with exogenous nuclear DNA admixture to the athlete's urine. Alternatively, taking in consideration the mitochondrial DNA, we could not exclude that a sibling or a maternal relative of the athlete could have acted as a donor of the urine utilized for doping control and DNA analysis. Both situations point to possible tampering of the urine by the athlete. Adjudication at CAS maintained previous national and international federation decision that there was no proof of a chain of custody flaw to justify the athlete's allegation of urine substitution after collection.
